This invention relates to im rovements in containers articularly well apted for use in the handling and distribution of hquefied petroleum gas, or the like, to consumers.

The Philfuels Company, of Bartlesville, Oklahoma, a subsidiary of the Phillips letroleum Company, have made the utilization of gas available to consumers remotely located from city gas mains, by a system of distributing liquefied etroleum gas to the consumer, which lique ed gas is highly volatile, and the vapor of which is used as fuel by the consumer. A consumers service 1nstallation requires a container for the liquefied gas, which must be economically produced for efiiciently receiving the liquefied gas against liability of leakage. The container must have liquid inlet and vapor outlet connections, and means is provided for weighing the container and the liquefied gas therein, in order to gauge the consumption; these features being more particularl set forth in the coending application, erial No. 280,746, filed ltlay 26, 1928.

In the present invention a metallic container of cylindrical form is provided, having improved connections in the top thereof for receiving inlet and outlet valves and a syphon tube, and provided with an improved connection axially thereof for supporting the container in a well balanced relation upon scales, for weighing purposes.

Other objectsand advantages of this mvention will be apparent during the course of the following detailed description.

In the drawing, wherein for the purpose of illustration is shown only a preferred embodiment of the invention,

Figure 1 is a side elevation of the improved drum or container.

Fig re 2 is a top plan view of the container.

Figure 3 is a vertical sectional view taken through the container substantially on the line 3-3 of Figure 2.

Figure 4 is a fragmentary sectional view of the top portion of the container.

Figure 5 is a fragmentary sectional view of a valve and tube connection for the container.

In the drawing, wherein similar reference characters designate correspondin parts throughout the several view s,the etter A may generally designate the container, which is of metal, including a cylindrical shaped body 10 and an integral dome-shaped to wall 11. The cylindrical body 10 is fabricated by the ordinary drawing process. The cylindrical bod 10 is of uniform diameter from end to en and in the lower end thereof is disposed a separate dome-shaped bottom wall 12, which fits entirely within the lower portion of the cylindrical body 10, bulging convexly downward but terminating at its apex short of thebottom edge 13 of the skirt portion 14 at the lower end of the cylindrical body 10. The dome-shaped separate bottom wall 12 is provided with an upstanding annular attaching flange 15 which may be secured in any manner, as by welding shown at 17 in the drawing, to the inner peripheral portion of the body 10, for connecting the bottom 12 in a leak-proof relation in the bottom of the cylindrical body 10. The container A strands upon its lower edge, upon a suitable foundation, which the bottom 12 does not contact.

The top wall 11 of the seamless steel portion of the container bulges convexly upwardly, and axially of the container, centrally on the top wall 11, there is provided a preferably polygonal nut 20, which is electric welded as at 21, but may be otherwise attached. It has a screw threaded socket 22 facing upwardly for detachable connection of a hook-shaped member 25, which receives the bail or suitable connecting link of weighing mechanism, by means of which the container, together with its liquid contents may be weighed for gauging purposes, as more particularly set forth in the co-pending application above mentioned. The nut 20, together with the detachable hook 25 is not only economical, but enables a facile weighing operation to take place.

Eccentrically in the top wall 11 of the container there are provided inlet and outlet connecting vents 30 and 31 respectively, preferably both adjacent the same side of the container, and not diametrically opposed with respect to the connection 25. The con- ,and 31 have screw threaded passageways 33 therethrough, wherein the screw threaded shanks of valves or the like may be disposed. The connection 31 receives an exterior valve thereon (not shown) for release of the gaseous vapor from the top of the tank. The sleeves and 31 are electrically welded at 37, in place upon the wall 11, in the relation mentioned, so that they are axially parallel with the axis of the tank. The connection 30 T receives a high pressure valve 50, which has an elongate screw threaded shank 51 detach- -ably threaded into the screw threaded passageway 33. The passageway 53 of the shank 51 of the valve 50 is provided with a' downwardly facing screw threaded socket 54 therein, adapted to detachably receive the upper screw threaded end 55 of a siphon tube or pipe 40, as shown in Figures 3 and 5 of the drawing. The relation of the valve and siphon tubes permits of the disconnection of both from the sleeve or nipple 30 simply by unscrewing the valve, and withdrawing the tubes. The tube 40 extends down within the container compartment, to within about one-half inch of the bottom wall 12.

In the filling of the container, the liquefied gas is entered through the connection 30 and gjalsgas downwardly through the tube 40 for g the tank. The gaseous vapor enters the customers service line through the connection 31. The tube 40 enables a ready siphoning of the liquefied contents of the "container, should it become necessary to empty the container;

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1. In a drawn metal container, a cylindrical body having a dome-shaped top wall, said top wall provided with an opening, the axis thereof parallel to the axis of the cylindrical body and to one side of the crown portion of the top wall, and an elongate intern'ally screw threaded sleeve fitting and extending through said opening, welded at its upper portion to the curved outer surface of p the top wall.

portion of the to wall, an elongate sleeve tting and exten g through said openingw1th the greater portion of said sleeve with-.

in said container, said sleeve welded at its upper portion to the curved outer surface of the top wall and provided with a screw threaded bore, and connection means including an elongate shank provided with sctew threads and detachably secured by said screw threads to said sleeve.

3. A closed drawn steel container having a convex surface, and a relatively small mass of metal welded on the surface preserving the convexi of the surface at that point, said mass 0 metal having a recess or hole therein, said recess or hole having such shape as to adapt it to receive a hook-like element, the longitudinal axis of the hook-like element passing through the center of gravity oft-he container.

4. A closed drawn steel container having 'a dome-shaped upper portion, and'a relatively small mass of metal welded on the apex portion of said dome-shaped portion without deformation of said portion, said mass of metal having a recess or hole therein, said recess or hole having such shape as to adaptit to receive a hook-like element, the longitudinal axis of the hook-like element passing through the center of gravity of the container.
